If a rumbling noise is heard from the engine, along with a possible loss in power, it may be caused by a collapsed hydraulic timing belt tensioner creating excessive cam backlash. Our technicians recommend replacing the timing belt and water pump at the same time, if they have not been recently replaced.
If the ABS light is on intermittently, it may be due to a loose ABS ring on the rear axle. If a loose ABS ring is found during inspection, replacement of the ABS ring and affected drive axle may be necessary.
